I knew it was documented somewhere but I couldn't find it last night. I did now, I think this was added in Market-Garden '44. From the changes.txt file, for its very first version:
- (Editor) Added ability to define a Release as "Fixing" which causes units
in the specified organization to become Fixed when the Release is
invoked.
- (Editor) Added ability to "tie" reinforcements together so they all
arrive at the same time by having all reinforcements in the group
after the first have an arrival probability of 0 (see Reinforce
Dialog in the Scenario Editor).
- (Editor) Added ability to define a reinforcement as "Check Once Daily"
which causes the arrival of the reinforcement to only be checked once
a day at the same time as the original arrival date.
And having read that, I see this is noted in the scenario editor help file (but not the user help):
When a reinforcement is defined with a probability of 0, then the arrival of that reinforcement is "tied" to the previous reinforcement for that side with a non-zero probability. When that reinforcement arrives, then all subsequent reinforcements tied to it arrive at the same time. If that reinforcement doesn’t arrive, then none of the reinforcements tied to it will arrive either. This allows a group of reinforcements to be defined that all will arrive at the same time.
One of those things from "before" your time David
